Like Dutchie007, I have tried other clients as well, and seem to keep going back to Thunderbird.

I would really like to solve the annoying font problem though.

Does anyone have any suggestions on how to easily increase font size so that the list of accounts and the titles of the emails are larger? I can increase the size of the email body but it's a bit of a pain in the butt too.

The add on I mentioned, theme font and size changer did what I want, but it seems everytime Thunderbird updates the addon gets broken and it takes forever to figure out how to get it working again.

As of now, I can't figure out how to get it to work. I can download the file and install it, but it still won't work.

Anyone have any experience with this addon that could help me?

I have my reading glasses on and I still have to squint to see the print.

Do any of the other clients mentioned have an easy way to increase font size?

What operating system are you using? In Windows you can go to the control panel and increase the display magnification. Go to System>Display. On the other hand, I really don't understand using desktop apps for email today. I have been using nothing but webmail for the last decade and vastly prefer it to any desktop program. At work I must use Outlook and it is not my favorite, but that is the obvious alternative that is available on Windows and Apple. To each his own.

I'm just tired of trying to increase font size in Thunderbird. I use theme and font size changer add on but it constantly breaks and I have to squint to see anything on the screen.

The font & size changer add-on(s) broke in Thunderbird 52.7.0. Earlier this year there was a problem where the add-on expired, and so somebody created a forked version that did not expire. Shortly afterwards the original author released another version.

The add-ons option menu works in 52.7 but no longer has any effect. What I did was switch to using a userChrome.css file to specify the font/font size for the toolbars/menus/folder listings etc. That works fine, even with betas and unreleased nightly builds.

See http://forums.mozillazine.org/viewto...8434#p14798434 (I'm tanstaafl in that forum) for a userChrome.css file that you can use. Use help -> troubleshooting information -> open folder to open windows explorer at your profile. Then create a chrome subdirectory (if it doesn't exist) and save the sample userChrome.css file in that subdirectory. Exit and restart Thunderbird. If the userChrome.css file changed the fonts/font sizes then use a text editor (NOT a word processor) to change 16pt (the font size) and Verdana (the font) to whatever values you prefer.

If it had no effect double check you created the file with the right name and in the right location. It would normally be something like:

With webmail on Windows 10 go to Settings>System>Display and choose to change default sizing up to 175%. Works OK with webmail, though I suspect it may cause rendering issues on many websites.

I set mine to 150% and it helped with my Thunderbird issue, but of course everything is larger now. Hopefully I can adjust to the new size. Yeah I'm sure I will run into rendering issues on some sites. Better than it was though.
